A standardized score scaled to a mean of 50 and a standard deviation of 10, making it easy to compare results across different tests or subjects. The formula is (score − mean) ÷ standard deviation × 10 + 50. When the standard deviation is small, even modest deviations from the mean produce a larger shift in the standard score.
